VISUAL STIMULATION CHANGES THE RATIO OF CONCENTRATIONS OF PARTICIPANTS OF THE GLUTAMINE-GLUTAMATE CYCLE IN THE ACTIVATED HUMAN CEREBRAL CORTEX

Abstract

A significant increase in the concentrations of Glu and Gln was found. Gln growth characterizes the activation of the Glu-Gln cycle in the visual cortex under constant stimulation. The increase in Glu in response to exercise is most likely caused by the activation of its synthesis.
